A small scale method for screening pectins in an acidified milk drink system

For testing of experimental pectins produced in very small amounts in acidi fied milk drinks, a small scale test system has been developed. The system only needs about 0.15 g of pectin per sample. The test system includes both a heat treatment and a homogenisation, and therefore resembles industrial production methods better than many test systems described in the literatur e. Measurements of viscometry, sedimentation and particle size of acidified milk drink were used to compare the small scale test system with a larger existing system. For all 3 properties an R-2 value of 0.89 or larger was ob tained between the 2 systems, using 6 different pectins.
